Sadly enough, I don't think it will ever become madatory either.
What I think would be a bit more realistic is this...
Anyone that chooses to have condom free sex should be required to hear the facts & statistics (either in a class type setting or one on one at a place like AIM) and should have proof that they have done this. They need to be educated on the effectiveness of condoms and the fact that testing won't always show positive results, even if the person is already infected and able to infect others.
In addition, these people should be required to sign something before every shoot, stating that they are aware of the risks and if they do end up contracting some sort of disease, they can't sue other actors, agents or producers and will also not be eligible for financial aid to treat the disease. They shouldn't be able to waste tax payers money because they were willing to take the risk.
